  • Patent number: 6925090
    Abstract: The present invention relates to a high-speed digital transmission method using an analog subscriber line (for example, an existing telephone-use copper cable), a subscriber accommodating system used in the high-speed digital transmission method, an accommodating device on a subscriber-terminal side and an accommodating device on an accommodating station side. The present invention includes the steps of providing a subscriber distributing device, to which a plurality of subscribers are connected, on a subscriber-terminal side of an analog subscriber line in a high-speed digital transmission method using the analog subscriber line; setting a low-frequency band part as a control channel; setting a high-frequency band part as one or a plurality of communication channels; and controlling the one or plurality of communication channels by use of the control channel. The plurality of subscribers communicate by using the same analog subscriber line.

  • Patent number: 6166746
    Abstract: An image processing apparatus has a three-dimensional joint position storing circuit for storing a three-dimensional coordinate position for each of available joints of an object at each frame for a standard action; a geometric data storing circuit for storing geometric data for at least a portion of the object based on unique coordinate systems for each of the available joints; a unique coordinate system determining circuit for determining the unique coordinate system for each of the available joints based on the stored three-dimensional coordinate positions; a three-dimensional joint angle computing circuit for computing a three-dimensional joint angle for at least one of the available joints based on a desired mode of action modification and the determined unique coordinate systems; a joint angle displacing circuit for displacing the three-dimensional joint angle for at least one of the available joints; a unique coordinate system generating circuit for generating the unique coordinate system for at least

  • Patent number: 5877778
    Abstract: A method and system for manipulating and mixing previously stored motion units for computer articulated figure animation. The motion units are combined in a weighted average. The weights give a priority to certain joint rotations of a motion unit which constitute the essence of that motion unit. The motion units can be mixed in an asynchronous fashion, with no limit on the number of motion units that can be mixed together. Phrasing control assigns a weight to each frame in a motion unit, and eases the transitions at the beginning and end of a motion unit. Frame-to-frame smoothing is also used. Fatigue of an articulated figure is simulated by the addition of a "tired" motion unit.
